Version 2.1.13 introduces a workaround for an intermittent issue (#351). Because of this, features “Highlight local variables” and “Highlight matching names” are off by default. You can turn them on from Tools => Options => Editor.

See the homepage for download links, and wiki for installation instructions.

Thonny plug-in system now allows installing separately packaged plug-ins (Tools => Manage plug-ins…). NB! I encourage you to try out a nice plug-in from Kauri Raba, which allows Thonny to use BBC micro:bit as its backend – see https://bitbucket.org/KauriRaba/thonny-microbit for more info.

UPDATE on 2017-05-04:Seems that in some cases at first run the cursor gets stuck somewhere, ie. no entry is possible neither in the shell nor in the editor. This was fixed in 2.1.1, but if you’re reading this, the upgrade is not actually necessary – just re-start Thonny and you’re done (you won’t meet this issue on next runs).
